Abstract

A display panel includes an array substrate, an opposite substrate and a liquid crystal layer disposed between the array substrate and the opposite substrate. A sensing array outputs an initial voltage in response to an initial thickness of the liquid crystal layer during an initializing time and a sensing voltage in response to a varied thickness of the liquid crystal layer due to external force during a sensing time. A control part compares the sensing voltage with the initial voltage, determines whether the external force is applied to the display panel, and generates information indicating a position to which the external force is applied. Thus, the display apparatus may improve sensing ability to an external signal inputted through the display panel thereof.
